WRENCH.

SPECIFICATION forming part of Letters Patent No. 320,357, dated June 16, 1885.

Application filed February 7, 1885.

To all whom it may concern Be it known that I, JACOB HUBER, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in 'renches; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accom panyin g drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to that class of inventions com monly known as monkey-wrenches, and has for its object to provide a simple construction by which the sliding jaw may be readily adjusted to and securely locked at any suitable point.

The invention consists, essentially, in the combination, with the shank having a segment of a thread and the sliding jaw, of a lockingsieeve encircling the shank and anextension of the sliding jaw, said sleeve being provided with a segment of a thread.

It further consists in certain novel constructions, which will be hereinafter more fully described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a side view, part in section, of my wrench. Fig. 2 is a detached section on line 00 00, Fig. 1. Fig. 3 is a detached section drawn through the arm of the sliding jaw. Fig. 4 is a front end view of the locking-sleeve. Fig. 5 is a detail view of a section of the shank; and Fig. 6 is a detail view of the looking-sleeve, all of which will be described.

The shank a is provided with the usually fixed jaw a, and has a suitable handle, (F. This shank is provided on its upper and lower sides with a segment of a thread, (0 and its two remaining sides are flattened, as shown.-

The movable jaw 11 is placed on and movable along the shank a. It is provided at its rear upper end with a pin, 0, for the purpose presently described. This jaw 12 is also formed with arms '17, which extend alongside of the shank a, and are lapped against the flattened sides of such shank, as shown in Figs. 1 and 2. At the rear end of these arms a retainingring, f, encircles the shank, and is detachably (No model.)

connected with the arms i, usually by means ofset-sorews g. The locking-sleeve d is placed on the shank, and fits between the rear end of the jaw b and the retaining-ringf. This sleeve is provided with an internal segmental thread, h, and with blank spaces h. The blank spaces h are of a length equal to the segmental threads a on the shank a.

In operation the sleeve, which may be rotated on the shank a, may be turned so as to make its threads h mesh with the threads a on the shank, or it may be turned so as to bring its blank spaces h to register with such threads. lVhen adjusted to the latter position,

the sleeve d may be moved along the shank a,

taking with it the wrench-jaw 1), until the latter has been brought to fit on a nut or bolt, when, by turning the sleeve d so as to mesh its threads h with the threads a? of the shank, the pitch of such threads will tighten the jaw 1) against the nut or bolt, and at the same time lock the slide-jaw in position.

I/Vhile I prefer to use the pitched threads, because by them I secure a tightening as well as locking of the jaw I), it is manifest that the locking of the said jaw might be secured by threads formed at right angles to the length of the shank, in order that the sleeve may be quickly meshed with the threads at. I prefer to form side threads, a pointed at their ends, as shown in Fig. 5. An equivalent of this construction would be the pointing of the threads h, in order that the sleeve may be stopped. In both its locked and unlocked positions I provide at its forward end shoulders e c, which are arranged on opposite sides of the pin 0 and engaged therewith when the sleeve is brought to its locked and unlocked position, so that the said sleeve is accurately stopped when its threads have been propcrl y engaged and operated to tighten the movable jaw, and also when the said sleeve is turned in such manner that the threads may clear the threads (6, in order to permit the free movement of the sleeve back and forth on the shank.

Vhile I prefer to use two segments of the threads h, and a corresponding number of the threads a, it will be understood that a single set of each of the threads might be employed without departing from the invention, and

tudinal s ctions, hinged at one edge, and pro-- vided at their other edges with suitable latch devices; or the said arms i and ring f might be dispensed with, and the locking-sleeve d be connected with the jaw by means of a tongue or projection on the one entering the groove of the other, asis employed frequently in connecting the adjusting-sleeve of the-ordinary monkey-wrench to the movable jaw. I prefer,

however, to employ the constructions shown,

because it may be easily and cheaply made. The armst' form a bearing for the lookingslceve, and such sleeve, being held by the ring f, may be quickly removed independently of the jaw, for any desired purpose.

It will be noticed that my wrench may be quickly adjusted to or locked in any desired position by placing the looking-sleeve on and encircling the shank. The said sleeve, in addition to its locking and tightening functions, serves effl'ciently as a handle by which to set the jaw back and forth, and by reason of its arrangement around the shank it may be readily moved along the shank without any of the clamping or binding actions likely to ensue when the jaw is moved by a construction arranged wholly on one or theother side of the shank.

Having thus described my invention, what 1. The combination of the shank provided with a segmental thread and having its sides flattened, the movable jaw provided with projections, and the locking-sleeve encircling said projections and rotating upon the shank, and

provided with an internal segmental threadand held to and sliding longitudinally simultaneously with the said jaw, whereby the latter may be adjusted along and locked at any desired point on the shank, substantially as set forth.

2. The combination of the shank provided with a segmental thread and having its sides flattened, the sliding sleeve encircling and rotating upon the shank, and provided with an internal segmental thread and having stopshoulders on its end next the movable jaw, the movable jaw held to and movable simultaneously with the sliding sleeve, and a checkpin or stop arranged on the jaw to engage with the stop-shoulders on and limit the rotation of the sleeve, substantially as set forth.

3. The combination of the wrench having two of its opposite sides flattened and provided with asegmental thread, the movable jaw having arms lapped along the flattened sides of the shank, the locking-sleeve encircling the shank having an internal segmental thread, and the retaining-ring encircling the shank in rear of the locking-sleeve and de tachably connected with the arms of the movable jaw, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

JACOB HUBEP.
